Alternator, Starter & Car Battery Replacement Services
Alternators
Your alternator powers essential systems while your engine is running. If your lights dim or your battery drains unexpectedly, it may be time for alternator repair or replacement. Our expert team will test your alternator and get you back on the road safely.
Batteries
Your car battery powers everything from the ignition to headlights. If you're jump-starting regularly or seeing a dashboard warning light, it's time to consider a car battery replacement. Our team offers fast battery testing, replacement, charging, and recycling services in Fremont. Not sure how often to replace a car battery? Most drivers should check their battery after 3 years and consider replacing by year 5-especially in extreme climates or with frequent short trips.
Starters
The starter gets your engine going. Clicking sounds or a failure to start can signal a faulty starter motor. We'll diagnose starter issues and repair or replace the component as needed to ensure reliable starts every time.
Car Starting FAQs
What sound does a bad starter make?
A failing starter often clicks when you turn the key-but it might also produce a grinding or whirring sound, or no sound at all. If your engine won't turn over, schedule a diagnostic with RST Automotive Inc. to determine if starter replacement is needed.
How do I unlock the steering wheel if it's stuck?
Apply pressure to the brake and turn the steering wheel slightly while turning the ignition key. This typically releases tension in the steering column and unlocks the wheel. If it doesn't work or the battery is dead, contact a professional to avoid damaging the ignition system.
Battery FAQs
What should I avoid when replacing a car battery?
When replacing a car battery, avoid letting tools bridge the terminals-it can cause sparks or electrical shorts. Make sure the battery is properly secured before connecting cables. Unsure how to replace a car battery safely? Our team is here to help with expert, affordable installation services.
What's the most common mistake when jumping a car?
The #1 mistake is connecting the jumper cables incorrectly-reversing the positive (red) and negative (black) leads can cause serious damage to your alternator or battery. Always double-check your connections and avoid using damaged or low-quality cables. If you're unsure, it's safest to let RST Automotive Inc. handle the jump-start for you.

What People Say About Us
I Brought my car in for an oil change. There was a light on the dash panel that I thought was just a reminder to change the oil. Turns out that it was Nissan's version of the check engine light. Roger and his team were able to diagnose the issue and clear the light. Always great service at RST!
I'd have to say after dealing with multiple mechanics in the tri-cities area that, hands down Roger is by far the most honest and professional mechanic I've dealt with to date, I'll be upgrading my 1971 corvette from a Muncie 4 speed to a Tremec 5-speed soon, I'll be contacting Roger again in the near future, to handle this project for me, I can count on his work, and he has the integrity to stand behind his work! Kudos to Roger and the RST staff!!

I brought my recently acquired American Clipper motor home in to have the coolant system flushed and the chassis lube. Roger took care of my needs on my old motor home and I want to continue to get the same service I have come to expect.
Thank you Roger & Jamie for providing excellent service! Our catalytic converter was stolen from our beloved RV. One of my tenants recommended us to them. Our CC was discontinued, but I was able to find a compatible one. Roger ordered it, delivered next day. We brought our RV in, and it was installed, caged. Not only that, we got it smog checked also. All in 1 DAY!! Thank you for helping us out, and providing speedy service. We will definitely will be back again for service on our RV! Thank-you!
I recommend Roger. He is an excellent mechanic and he does specialize in older cars which is what I have so that's helpful for me as well. Prices tend to be on the more expensive side, but with the older car I previously had, he was one of the few who could fix it.
RST has taken care of my truck since it was born. I trust no one else to work on the truck. When they tell me my vehicle is safe and running well, I feel so secure. I am 84 years old and safe and secure is a MUST. 5 stars does not seem enough.
